Customer Success Stories
Virtual Office Support
Our client, a successful Japanese medical equipment manufacturer, needed to compete locally in an increasingly competitive U.S. market.
U.S. sales were declining due to increasing competition from local traders and manufacturers.

Expatriate Payroll Processing
Our client, a holding company with 30 expatriates and three local employees was suffering under the burden of complicated payroll processing. Japanese salaries and non-monetary salaries had to be grossed up along with U.S. salaries.
Our client needed to perform gross-up calculations on salaries, allowances, and non-monetary benefits while in the U.S. This operation was being handled by a human resources representative from Japan but he needed support. Additionally, the company wanted to keep expatriate salaries confidential.

Our client’s senior management was seeking ways to handle their accounting department’s AP and AR functions in a more cost-effective, centralized, and efficient way.
- As a large-scale business, AP and AR functions were segregated and inefficiently spread out among multiple employees.
